Configuring a port as a simulated member host
Generally, a host that runs IGMP can respond to IGMP queries. If a host fails to respond, the
multicast router might deem that no member of this multicast group exists on the subnet, and
removes the corresponding forwarding path.
To avoid this situation, you can configure the port as a simulated member host for a multicast group.
When the simulated member host receives an IGMP query, it gives a response. Therefore, the switch
can continue receiving multicast data.
A simulated host is equivalent to a real, independent host in the following ways:
•
When a port is configured as a simulated member host, the switch can send an unsolicited
IGMP report through the port. It can also respond to IGMP general queries with IGMP reports
through the port.
•
When you disable the simulated joining function on the port, the switch sends an IGMP leave
message through the port.
To configure a port as a simulated member host:
Step Command Remarks
1.
Enter system view.

N/A
2.
Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view, or
enter port group view.
•
Enter Layer 2 Ethernet interface view
or Layer 2 aggregate interface view:
interface
interface-type
interface-number
•
Enter port group view:
port-group

Use either command.
3.
Configure the port as a
simulated member host.

Not configured by default.
NOTE:
Unlike a static member port, a port that you configure as a simulated member host ages out like a
dynamic member port.
